@michaelmitchell it is and it isn't. From our analytics, we can see that there really aren't many people using it (or app.net in general), but: I'm working on a Twitter port at the moment. Who knows what the future holds, though!

@abraham the bummer part is, from what I can tell looking at the numbers, the near-entirety of remaining traffic is bots/IFTTT/Buffer/PourOver.
(Bots didn't care about the SotU blog post, but people did.)
